Fitbit Charge 4 and Fitbit Sense
While the Fitbit Charge 3 is not quite old, the Charge 4 is the latest. The cost and battery life of both the trackers are the same. Still, the Charge 4 also provides built-in GPS, automatic workout detections, SpO2 monitoring, Spotify controls and even contactless payments. Charge 4 is a better bet than Charge 3 since it offers better features for the same rate.
The Fitbit Sense, on the other hand, launched along with Versa 3. Initially, the cost of the Fitbit Sense was more than Versa 3, but now the official Fitbit website prices them at the exact cost. Sense provides an ECG app along with EDA scan apps that help keep better track of stress levels. At this given point, Fitbit Sense would be a better option than the Versa 3, given that they are equally priced now.
Overall, all the four devices mentioned above – Fitbit Charge 3, Charge 4, Versa 3 and Sense, share almost the same basic features. In contrast, Charge 4 and Fitbit Sense have a few advantages over Charge 3 and Versa 3, respectively, based on your usage and requirements.
